Dear Customer, You can follow the below steps to change your domain: Step 1: Add the New Domain Name
- Check Availability: Ensure the new domain you want is available. For example, if you want your SharePoint and OneDrive URLs to begin with fabrikam.sharepoint.com, enter https://fabrikam.sharepoint.com in a browser. If you get a message that the address couldn’t be found (404), it’s probably available.
- Add the Domain: Add your new .onmicrosoft.com domain using the Domains page in the M365 Admin Center. Do not use the "Add domain" option directly present in the Domains page, as it does not create a .onmicrosoft.com domain.Step 2: Use Microsoft PowerShell to Rename Your Domain1. Download the Latest SharePoint Online Management Shell: Ensure you have the latest version installed.
- Connect to SharePoint: Connect to SharePoint as at least a SharePoint Administrator in Microsoft 365. Connect-SPOService -Url "https://contoso-admin.sharepoint.com"
- Run the Rename Command: Use the following command to specify the new domain name: Start-SPOTenantRename -DomainName "fabrikam" -ScheduledDateTime "2025-4-17T10:25:00" Ensure the ScheduledDateTime is at least 24 hours in the future but not more than 30 days. Step 3: Prioritize Sites (Premium) If you have SharePoint Advanced Management licenses, you can prioritize up to 4,000 sites for early execution using the Set-SPOTenantRenameSitePrioritization cmdlet. Step 4: Monitor the Status of the Rename You can get the status of the rename by running Get-SPOTenantRenameStatus. During and after the rename, you can get the state of a site by running Get-SPOSiteRenameState. Step 5: Review Features and Settings After the Rename Review any firewall rules, browser settings, third-party apps, custom apps, and scripts that access SharePoint. They might need to be modified to use the new domain. Important Considerations
